▷ (Immediate Start) Senior Data Scientist - RelayNetwork

Company mission In the future, almost everything weconsume will simply materialise on our doorsteps – what we call“e-commerce” today will simply be “commerce” tomorrow. But if wecontinue on today’s trajectory, the growth of e-commerce risksdamaging the environment, alienating our communities, and strainingthe bottom-line for small businesses.

By buildingfrom the ground up we are able to entirely rethink both the middleand last mile enabling us to reduce the number of miles driven todeliver each parcel, lower carbon emissions, and lower costs, allwhile channelling funds to community members. At the same time,we’re fixing the last broken aspect of e-commerce for consumers:delivery.
